I purchased a new MediaTek GPS from the store and am curious about the specifications on it. The GPS unit itself can run at up to 5.0V but there is no documentation showing that the adapter board can run at 5.0V. Looking around on other threads, I'm wondering if it's limited to 3.3V as that seems to be what I have read. What further confuses me though is that the bottom of the board where it has the solder pads shows VCC to be 5V. What are the specs for this unit?
Another question is that I see on the store that there is example code to read data from this GPS for a standard Arduino. I would like to test it out just to make sure I don't have a problem with the GPS. Assuming the adapter board can take 5V (that's why I ask above), I only need to upload the example code to the Arduino, then connect VCC and GND of the GPS to the board and then OUT from the GPS to Serial in 0 correct? I will be using an Arduino Pro to test it out.
One last question, when updating the firmware on the GPS, I know you need an FTDI cable of some sort and I have one but it's a 5.0V version that I have so if the adapter board doesn't take 5.0V, how am I supposed to update it?
Thanks. I'm excited to be able to connect the GPS up to the ArduPilot tomorrow once I can open it and go from there. Until then, I'll be testing the GPS out to see if I can get any data from it.
